Installing the unit
________
5.1 Electrical connection
Before connecting the unit to the power supply, check that the electrical grid characteristics match those
described in the technical characteristics of each unit. The electrical installation must be performed by authorised
technicians and meet the regulations in force.
Preferably, the electrical connection should be performed by mounting and electrical outlet of appropriate type
and capacity for the maximum current absorbed by the oven phases. If not possible, it could be directly connected to the
circuit breaker on the electrical control board.
In order to prevent damages from unintentional reset of the power failure thermal device, this unit should not be
fed by an external control device, such as a timer, or be connected to a circuit whose supply is regularly interrupted.
An own power supply line protected by an adequately sized magneto-thermic switch and a fixed supply
connection is recommended.
Observe the colour code of cables. Inappropriate connection may damage the unit.

Models RX 604, RX 604 Plus and M 604 Plus allow switching the type of connection from three-phase 400 Vac to
single-phase 230 Vac or vice versa, and from three-phase 400 Vac to three-phase 230 Vac or vice versa. To do so,
refer to the connection diagrams below and follow the following steps.
